What is volcanic ash made of.

Volcanic ash is a mixture of rock, mineral, and glass particles expelled from a volcano during a volcanic eruption.The particles are very small—less than 2 millimeters in diameter. They tend to be pitted and full of holes, which gives them a low density.Along with water vapor and other hot gases, . volcanic ash is part of the dark ash column that rises above a volcano when it erupts.When volcanoes erupt explosively, vast amounts of lava, rock, ash, and gases are thrown into the atmosphere. The solid parts, called tephra, settle back to earth and cool into rocks with pyroclastic textures. Pyro, meaning fire, refers to the igneous source of the tephra and clastic refers to the rock fragments.A volcano is a mountain that opens downward to a pool of molten rock below the surface of the earth. When pressure builds up, eruptions occur. Gases and rock shoot up through the opening and spill over or fill the air with lava fragments. Eruptions can cause lateral blasts, lava flows, hot ash flows, mudslides, avalanches, falling ash and floods.Volcanic ash is a combination of fine particles made of rock, tiny strands of supercooled lava called volcanic glass, and minerals. The particles are usually smaller than an inch in diameter, but ...
